Qatar Airways Medical with Restrictions
Oblivion ; You will find it difficult to "hide" an existing Class one OML, wherever it comes from. Just pitching up , expecting no background history check is a bit naive.
Developing a condition to OML status within an airline is, usually well tolerated and handled. Joining, with existing OML is, mostly, not acceptable.
Honesty is good and less likely to have re[ercussion. Show QR that you are honest. Show that the OML restriction is very rare. OML's give Rostering a head-ache because they cannot roster two OML's together. That's all. Try showing QR that it is most unlikely that anyone else in the company has the same condition anyway.
A worthy fight is with your CAA. The likelihood of your condition re-surfacing, being so rare, should give strong reason to remove the OML. But, oh dear, they hate being told (!)
